What is WAI-ARIA?

WAI-ARIA, often referred as ARIA, is an abbreviation for Web Accessibility Initiative - Accessible Rich Internet Applications Suite. In early 2014, WAI-ARIA became a completed World Wide Web Consortium (W3C) recommendation. WAI-ARIA is a technical specification that specifies a way of making websites more accessible to people with disabilities.

WAI-ARIA specifies certain attributes that can be added to a website’s HTML code to give information on how an element should be interpreted on a speech based interface, e.g. telling a screen reader that something is a button or a navigation area. WAI-ARIA especially helps with dynamic content and advanced user interface controls developed with, for example, JavaScript.
